Amazing Animals Facts — Surprising Wildlife Facts for Everyone

The Killer Whale ( Orcinus orca ) is the fastest sea mammals. It speeds through the ocean at 45 kilometers per hour (km/hr). The killer whale hunts fish and larger mammals. It has a mouthful of pointed teeth shaped to hold slippery food  like squid. A killer whale is also known as the Orca. They hunts in packs. So also known as wolves of the sea. Killer whales are regarded as apex predators, lacking natural predators and preying on even large sharks.  Like dolphins, orcas use echolocation i.e. bouncing sound off of objects to determine their location  to hunt and use a series of high-pitched clicks to stun prey. Orcas are very fast swimmers. They can swim up to 30 mph Recent studies have found that orcas are among the most contaminated marine mammals in the world. Pollution and chemical contamination make orcas more susceptible to disease and likely cause reproductive difficulties. The IUCN currently assesses the orca's conservation status as data ...

The white sturgeon Acipenser transmontanus also known as the Pacific sturgeon, Oregon sturgeon, Columbia sturgeon, Sacramento sturgeon, and California white sturgeon. It is the largest freshwater fish in North America and is the third largest species of sturgeon, after the Beluga and the Kaluga. The white sturgeon has a slender, long body, head and mouth. This fish has no scales; instead it has large bony scutes that serve as a form of armor. A sturgeon's taste buds are located on the outside of its mouth. The underside is a clean white. It can smell food with four barbels, used for sensing food, near its huge toothless mouth.  White Sturgeon can live to be over 100 years old. White sturgeon in the Kootenai River are at such a low level that they were listed as endangered under the Endangered Species Act in 1994.  In addition to overfishing, dams constructed along the Columbia and Snake Rivers have also become a threat to sturgeon. Tribal fishery managers ...

Lice (singular: louse)  Pediculosis capitis or head lice. The order has traditionally been divided into two suborders, the sucking lice (Anoplura) and the chewing lice (Mallophaga)the Mallophaga are paraphyletic and four suborders are recently recognized: Anoplura: sucking lice, occurring on mammals exclusively. Rhyncophthirina: parasites of elephants and warthogs. Ischnocera: mostly avian chewing lice- one family parasitizes mammals. Amblycera: a primitive suborder of chewing lice, widespread on birds. Most lice are scavengers, feeding on skin and other debris found on the host's body, but some species feed on sebaceous secretions and blood.  Head lice are tiny insects that live on the skin covering the top of your head, called the scalp.  They are not dangerous and do not cause any bodily harm.  Lice can be spread by close contact with other people.  Head lice infect hair on the head. Tiny eggs on the hair look like flakes of dandruff. However, instead of ...

A jellyfish is 98% water. Jellyfish also known as jellies or sea jellies or a stage of the life cycle of Medusozoa are free-swimming members of the phylum Cnidaria.  Medusa is another word for jellyfish.  Jellyfish are classified in the phylum Coelenterata, which means they have a very simple body with a large center mouth where food comes in and waste goes out. Jellyfish have tiny stinging cells in their tentacles to stun or paralyze their prey before they eat them. Sea turtles relish the taste of jellyfish.  Jellyfish are invertebrates and don't have a backbone. All jellyfish sting, but the stings of small specimens and those with short tentacles often are not painful to humans. Even dead jellyfish can sting. One of the smallest adult jellies is the Australian Irukandji, which is about the size of a fingernail. The lion's mane jellyfish, Cyanea capillata, were long-cited as the largest jellyfish. The rarely-encountered deep-sea jellyfish Stygiomedusa gigantea is another...
